Hybrid cryptography algorithms for enhanced adaptive acknowledgment secure in manet

The mobile adhoc network is a group of mobile nodes without having the fixed infrastructure. Due to the infrastructure less network and distributed nature, make mobile adhoc network susceptible to malicious attackers. So, we use an intrusion detection system called Enhanced Adaptive ACKnowledgement (EAACK) especially for mobile adhoc networks. Based on the digital signature algorithm (DSA) and RSA the EAACK is designed. To enhance the strength of the security in the mobile adhoc networks, we introduce an innovative approach called Hybrid Security Protocol that provides integrity, confidentiality and authentication. This Hybrid Security Protocol consists of Cryptography based on Elliptic curve, Dual-RSA algorithm and Message Digest MD5. Encryption is achieved by using Elliptic Curve Cryptography, Dual-RSA algorithm for authentication and MD-5 for integrity. By using a combination of both symmetric and asymmetric cryptographic techniques, we achieve better security with integrity.

Incidental discovery of a developmental venous anomaly: a case report of a 37-year-old female with chronic headaches

Developmental venous anomalies (DVAs) are congenital vascular malformations often found incidentally on neuroimaging. This case report describes a 37-year-old female with chronic headaches and an incidentally discovered DVA in the left frontal lobe. Magnetic resonance imaging (MRI) revealed a classic "caput medusae" pattern without hemorrhage or associated cavernous malformation. This case highlights the importance of recognizing DVAs as incidental findings, differentiating them from other causes of chronic headaches, and understanding the significance of associated imaging findings.

N-gram and k-nearest neighbour based igbo text classification model

The evolution in Information Technology has gone a long way of bringing Igbo, one of the major Nigerian languages evolved. Some online service providers report news, publish articles and search with this language. The advancement will likely result to generation of huge textual data in the language, that needs to be organized, managed and classified efficiently for easy information access, extraction and retrieval by the end users. This work presents an enhanced model for Igbo text classification. The classification was based on N-gram and K-Nearest Neighbour techniques. Considering the peculiarities in Igbo language, N-gram model was adopted for the text representation. The text was represented with Unigram, Bigram and Trigram techniques. The classification of the represented text was done using the K-Nearest Neighbour technique. The model is implemented with the Python programming language together with the tools from Natural Language Toolkit (NLTK). The evaluation of the Igbo text classification system performance was done by calculating the recall, precision and F1-measure on N-gram represented text. The result shows text classification on bigram represented Igbo text has highest degree of exactness (precision); trigram has the lowest level of precision and result obtained with the three N-gram techniques has the same level of completeness (recall). Bigram text representation technique is extremely recommended for any text-based system in Igbo. This model can be adopted in text analysis, text mining, information retrieval, natural language processing and any intelligent text-based system in the language.

Comparative energy scheduling and efficiency analysis of 150kw hybrid micro-grids using ann-pso

This study investigated the formulation, implementation, and performance implications of an artificial neural network–particle swarm optimization (ANN–PSO) based energy scheduling framework for a 150kW hybrid micro-grid. The analysis focused on two hybrid configurations, namely micro gas turbine–fuel cell (MGT–FC) and solar photovoltaic–battery storage system (PV–BSS), with emphasis on optimal dispatch behaviour and system efficiency under dynamic load and generation conditions. MATLAB was used to simulate ANN-based forecasting of hourly load and distributed energy resource outputs, which were subsequently optimized using PSO over multiple iterations to achieve balanced supply–demand scheduling. 4-in-1 visualization techniques were employed to capture convergence behaviour, transient response, dispatch stability, and efficiency dynamics across operating scenarios. Results showed that both hybrid systems achieved convergence within 20–24 PSO iterations, with scheduled power maintained within 50–120kW despite injected disturbances of ±20–30kW. The MGT–FC configuration demonstrated smoother dispatch profiles and faster fitness convergence, while the PV–BSS system exhibited greater variability due to intermittency, compensated by storage dispatch. Efficiency analysis revealed that optimal ANN–PSO scheduling sustained MGT–FC efficiency within 83–89%, whereas PV–BSS efficiency ranged between 41–72%, peaking during high-irradiance periods. Overall, the findings established that ANN–PSO-based scheduling enhanced operational stability and efficiency in both configurations, while highlighting the superior resilience of the MGT–FC hybrid under identical dynamic conditions. The study concluded that intelligent optimization provides a viable pathway for improving micro-grid performance in developing communities and industrial off-grid applications, where reliable and efficient decentralized power supply remains critical. It was therefore recommended among others that power system engineers and industrial energy planners in developing economies adopt ANN–PSO frameworks for real-time micro-grid dispatch to improve efficiency, resilience, and adaptability of decentralized energy systems serving communities and industrial loads.

Acute cardiorenal syndrome: review (part 2)

Recently, the definition of cardiorenal syndrome (CRS), a condition with a complicated pathogenesis, has been revised. Logically, CRS syndrome should be classified according to the initial organ that is injured, resulting in damage to another organ. Hence, there are only three main categories of CRS. Category one includes acute and chronic CRS. Category two involves renal-cardiac syndrome (RCS), which can be classified as acute or chronic. The third category represents secondary CRS, referred to as cardio-reno-cardiac syndrome (CRCS), which can be subdivided into acute and chronic CRCS. In this part of our series, we will discuss the epidemiology, pathophysiology, diagnosis, treatment, and prevention of acute CRS. We retrieved articles published on acute CRS using different keywords and phrases between January 2019 and June 2025 to achieve these goals.

The moderating effect of social support on the association between healthcare discrimination and quality of life in persons with type 2 diabetes

Background/Objectives: Healthcare discrimination poses significant challenges to the health-related quality of life (HRQoL) of people living with type 2 diabetes (T2D). However, the role of social support in alleviating these effects has not been fully explored. Drawing on Cohen and Wills’ social support buffering model, this study examined whether social support moderates the association between healthcare discrimination and HRQoL among individuals with T2D. Methods: We analyzed data from 5180 adults with T2D enrolled in the All of Us Research Program. Healthcare discrimination was assessed using the modified Everyday Discrimination Scale (mEDS), social support with the Medical Outcomes Study Social Support Survey (MOS-SSS), and HRQoL (physical and mental domains) with the PROMIS Global Health Scale. Moderation analyses were conducted through linear regression models. Results: Greater exposure to healthcare discrimination was associated with poorer physical and mental HRQoL. Social support demonstrated a significant moderating effect on mental HRQoL: as social support increased, the negative association between healthcare discrimination and mental well-being weakened. However, this buffering effect was not observed for physical HRQoL. Conclusions: Findings suggest that social support can mitigate the adverse mental health consequences of healthcare discrimination among individuals with T2D. Interventions aimed at strengthening social support networks warrant investigation as potential strategies to improve the mental HRQoL of people with T2D who encounter discrimination in healthcare environments.

Determination of the rich structural wave dynamic solutions to the caudrey–dodd–gibbon equation and the lax equation

This article addresses the implementation of the new generalized (G'∕G)-expansion method to the Caudrey–Dodd–Gibbon (CDG) equation and the Lax equation which are associated with the fifth-order KdV (fKdV) equation. The method works well to derive a variety of standard and functional closed-form wave solutions with distinct physical structures, such as, soliton, kink, periodic soliton, and bell-shaped soliton solutions. The solutions obtained using this method are useful and adequate than other methods. In order to understand the physical aspects and importance of the method, the attained solutions have been simulated graphically. The extracted results definitely establish that the new generalized(G'∕G)-expansion method is an effective mathematical tool to work out new solutions to different types of local nonlinear evolution equations emerging in applied science and engineering, but this method is not effective in solving nonlocal equations.

Beliefs and practices in taking licensure examination for teachers as spectrum of teachers’ moral principles: a case probe

The study employed Appreciative Inquiry framework to have an in-depth investigation in the personal lives of the participants and to draw connections between their beliefs and practices in taking Licensure Examination for Teachers and how these superstitions reflect and affect their moral principles. Specifically, it aimed to: (1) determine the superstitious beliefs followed by the examinees before, during, and after taking the Licensure Examination for Teachers (LET); (2) determine the positive and negative impact of these superstitions in the aspect of taking LET; and, (3) identify the effects of these superstitions in the characters and principles of the teachers. Semi-structured interview and focus group discussion were used and the data-sources were triangulated to come-up with a stronger analysis. Audit trail and member checking were followed to ensure that there were no biases in the interpretation of the data and to establish the validity of the results. Findings revealed that the student examinees followed different superstitious beliefs before, during and after the exam which have positive and negative effects. The motive of avoiding failure in the examination predominates over the motive of achieving success. The positive and negative effects of superstitions vary from one person's experience to another. Moreover, the assertion and personal disposition to pass the exam became the product of student examinees' projection. The superstitious notions were initiated to discard the student examinees' fears and to safeguard their emotional sphere against negative feelings and any untoward possibilities. Meanwhile, in the development of moral principle, the student examinees' family, peers and the society are important factors in the establishment of their belief system which later on reflects the moral principles they uphold.

Occurrence of hypopituitarism in tunisian turner syndrome patients: familial versus sporadic cases

Objective: To explore unusual association between Turner Syndrome (TS) and Hypopituitarism in a Tunisian cohort. Methods: We reported 6 patients with TS associated to Hypopituitarism, including three familial cases except the fourth sister who showed only a TS phenotype. Biochemical analysis, resonance magnetic imaging and cytogenetic analyses were performed. Results: The average age of our patients was 17.2 years (11-31 years). They were all referred for short stature and pubertal delay, except for the fourth sister who presented spontaneous puberty with the integrity of the pituitary axis and the presence of an X ring chromosome. Karyotype analysis showed monosomy in 3 cases and a mosaic TS in the 3 remaining cases, including one patient with abnormal X chromosome structure. Somatotropic and corticotropic deficiencies were confirmed in 2 sporadic cases while the gonadotropic and thyrotropic axes were spared. In contrast; familial cases were consistently affected by the integrity of the corticotropic axis. MRI showed pituitary hypoplasia in all familial cases and pituitary stalk interruption syndrome in only one sporadic case. No correlation was found between the chromosome formula and the anterior pituitary involvement. Conclusion: Co-segregation of congenital Hypopituitarism with pituitary hypoplasia and X chromosome aberrations could imply a molecular anomaly of transcription factors responsible for the differentiation and development of pituitary cells such as PROP1, POUF1, Hesx1, Lhx3, Lhx4. The etiopathogenic link between X chromosome abnormalities and the occurrence of Hypopituitarism remains unclear; however, the progress of molecular biology may clarify the interrelation between transcription factors and sex chromosome segregation abnormalities.

Inhibition of calcium oxalate crystals growth by macrotyloma uniflorum (lam.) verdc, phaseolus lunatus linn, and phaseolus vulgaris linn: an in vitro study

Purpose: The study aims to explore all possible morphological features of calcium oxalate monohydrate and calcium oxalate dihydrate crystals and their habits in case of inhibition. Methods: The study was carried out on a glass slide to observe the growth and inhibition of calcium oxalate monohydrate (COM) crystals by using infusions (5-20%) of Macrotyloma uniflorum (Lam.) Verdc, Phaseolus lunatus Linn. and Phaseolus vulgaris Linn. The reagents of the double diffusion gel technique were used for this purpose. Results: Calcium oxalate crystals are divided into three types: calcium oxalate monohydrate, dihydrate, and trihydrate. These types are further divided into sub-types based on their morphology. In the case of calcium oxalate monohydrate (COM), these crystals are donuts, dumbbells, needles, platy, prismatic, rosette, round edges and X-shaped. Calcium oxalate dihydrate (COD) is the elongated large rods and tetragonal bipyramidal forms. In the present study, dendritic or arborescent (tree-like platy crystals) were observed for the first time as part of a COM growth. Long chain loose agglomerates and compact aggregated crystals are the typical pattern of calcium oxalate crystals. All tested infusions caused growth inhibition of calcium oxalate crystals. Smaller nucleation zones and defective shapes of the grown crystals are declared different growth inhibition patterns. Conclusion: This study gives extensive information about morphology, aggregation and growth inhibition of calcium oxalate crystals.

Schwannoma with an unusual anterior chest wall location: a rare case report

Chest wall schwannoma is a rare intercostal nerve tumor originating from Schwann cells. Here, we present a case of a 44-year old woman who presented with symptoms of cough, fever, and left-sided chest pain. A plain chest radiograph was unremarkable and was further evaluated with a contrast-enhanced chest computed tomography (CECT) scan, which showed a well-defined, encapsulated soft-tissue mass in the left anterior first intercostal space. The diagnosis of schwannoma was based on histopathological and immunohistochemical studies of tissue biopsies taken from the lesion. The patient was referred to a higher oncology center for further treatment where he received symptomatic treatment for the pain and cough after which he improved. The patient was discharged and followed up in the clinic. Six months later, the patient underwent another chest CECT, which revealed no growth in size from the first one. Therefore, it was decided to keep the patient in regular follow-up since the lesion remained stable in size.

Use of over the counter medications among adolescents

Improper use of medicines may carry possible health dangers and more evidence continues to stand that adverse drug reactions to medicines are common but often preventable. Self-medication phenomena with over the counter medicines is common among people. It is regarded as essential issue of self-care. Over the counter medicines use such as analgesics among children and adolescents is continuously increasing in Libya. This constitutes an important public health concern. The aim of this study is to focus on adolescent's self-medication phenomena about the over the counter medicines that teens frequently used to treat minor and serious diseases. This work collected information throughout survey-comprised number of questions for the teenagers bought medicines from private pharmacies at two different secondary schools in Benghazi city, Libya, without prescription. The sample size was 120 students, 58 males and 62 females in age range of 15-18 years. Data collected from questionnaire were analyzed for pattern of medicine use. Male adolescents bought toothache and muscle-spasm medicines more frequently than female adolescents. On the other hand, female adolescents administered more over the counter medications monthly than males. The use of over the counter medicines has been found highly rated and exaggerated among secondary school teenagers. In conclusion, adolescents have to be educated regarding over the counter medicine use in Libya. The need for promoting the appropriate use of medicines healthcare system is an important issue. This can be achieved through an educational strategy involved different public sectors such as health and education authorities.

Metronidazole-induced neurotoxicity: is iron a contributing factor?

Metronidazole-induced neurotoxicity is a rising challenge in managing susceptible infections. The mechanisms involved in metronidazole-induced neurotoxicity are not fully unraveled. This study aimed to explore the effect of metronidazole on iron homeostasis in SH-SY5Y neuroblastoma cells. Confluent SH-SY5Y neuroblastoma cells were treated with different concentrations of 1.0, 10, 25, 50, 100, and 250 µM of metronidazole only or in combination with 20 µM iron. DMSO or culture media was used as control. Viability and ferritin assays were conducted on the treated cells. The treatments were for 24 hours, 48 hours, and 72 hours, respectively. In the viability assay, doses of metronidazole reduced the viability of SH-SY5Y neuroblastoma cells in a time and concentration-dependent manner. After 24-hour treatment, 250 µM metronidazole significantly reduced cell viability while 50 µM, 100 µM and 250 µM metronidazole reduced considerably viability only after 48-hour and 72-hour compared with control. Different doses of metronidazole 50 µM, 100 µM, and 250 µM in 20 µM iron reduced viability in a time-dependent manner in all the test periods. Metronidazole also induced a time- and concentration-dependent increase (p<0.05) in cellular iron uptake in the 48-hour and 72-hour treated cells in concentrations above 25 µM metronidazole. It is concluded that metronidazole induces a time and concentration-dependent iron overload and consequent cell death in SH-SY5Y neuroblastoma cells and this may contribute to the mechanism of metronidazole-induced neurotoxicity.

La surenchère lexicale dans le ventre, le pain ou la cendre de tchicaya u tam’si

Cet article porte sur l’ouvrage Le ventre, le pain ou la cendre de Tchicaya U Tam’si. À partir des approches linguistique, stylistique et sémiotique, nous avons tenté de montrer, dans notre analyse, en quoi l’écriture de ce recueil construit des stratégies discursives propres à retenir l’attention du récepteur. À cet effet, nous avons relevé deux principales figures de rhétoriques à savoir, l’emphase et l’hyperbole. Ces deux procédés de style produisent d’une part un effet d’insistance du procès poétique ; et de l’autre, un effet d’amplification du langage poétique.
